Carbon fibre/fibreglass is pretty easy to work with. just make sure you mask with tape around the area you're going to cut, helps from chipping/cracking the area you don't want to damage. Dremel or die grinder will be your best friend.
I'm installing my aerocatch bonnet pins on my gtr bonnet at the moment. Only have a die grinder and because the bonnet is aluminum, when it heats up it melts onto the die grinder, makes it a very long process.
